Well...got into it today...but not much...I expect when I do the engine clean I'll see it more...BUT...a couple of blasts of WD40 later (it is a penetrating fluid)...
D15B1 appeared!
I didn't really get a look at the other numbers...but now I know for sure...D15B1.


Thanks for the help guys...and the great "visual aids"...greatly appreciated!
